The free ends of the legs of a chair, and particularly the two rearones, as they are at the present time ordinarily made, are comparativelysmall and although usually round, have nevertheless sharp angles. Duringthe period of time during. which they are ordinarily used this might beof no marked disadvantage. But during long sessions, or periods of usein the same chair, such as during usual card games, dominoes and thelike, and around waiting rooms in offices, depots and the like, theoccupants become tired and are apt to change their positions, and totilt the chairs. During such use the linoleum and other coverings becomeout and partially perforated, from contact with the chair legs.

In a short time the general surfaces of such coverings become so cut upas to require new floor coverings, and before such replacement is made,present anything but a smooth surface.

The use of my device obviates all of the disadvantages above enumerated,and in addition furnish much comfort to the occupant by giving him manypositions in which to use the chair in comfort.

The machine illustrated in the accompanying drawings is a highlypractical embodiment of a machine adapted for the slicing and wrappingof loaves of bread or for the wrapping of unsliced loaves. While certainfeatures are especially designed for embodiment in,such a machine,others are highly desirable for use without the combination feature andfor wrapping articles other than bread.

The main frame I of the machine is of suitable form and dimensions tosupport various operating parts and is provided with a forwardlyprojecting top portion 2 which overhangs a part of the adjustable frame3. The base 4 for the main frame I is provided with a lateral extension5, this lateral extension and the main frame having tracks or ways 6thereon disposed transversely of the machine and on which the slicingmachine designated generally by the numeral I is mounted.

The slicing machine is provided with rollers or carrying wheels 8traveling on the track or way 6 so that the slicing machine may be movedinto operative position and the bread passing into the machine isdelivered thereto. The slicing machine is shown in operative position inFig. 1 and in inoperative position in Fig. 3.

The adjustable frame 3 is slidably supported at its inner end on thepedestals 9 and at its forward or outer end on the pedestals or uprightsl0 which have slide bearings ll coacting with the slides l2 on theframe. The frame has slides 13 coacting with the slide bearings I4 onthe pedestals 9.

The overhanging top portion 2 of the main frame is supported by the siderails or extensions l5 mounted on the upper ends of the pedestals ill,see Fig. 2. The adjustable frame is mounted for adjustment so that whenin one position the slicing machine unit may be adjusted to operativeposition, and, when the slicing machine unit is withdrawn or ininoperative position as shown in Fig. 2, this frame may be adjusted toits inner position into cooperation with other parts of the feedingmechanism.

In this description I have treated the portion of the machine shown inFig. 2 as the front end of the machine, inasmuch as the loaves orarticles to be wrapped are fed into the machine from that end. It willbe understood, however, that the articles are also discharged in wrappedcondition from the same end of the machine. The unwrapped articles aredesignated by the numeral it while the wrapped articles are designatedby the numeral ll.

I'will first describe the path of the articles through the machine andthen describe the several mechanisms in detail.

The loaves of bread or other articles 'to be wrapped or operated uponare placed by hand or delivered automatically upon a feed conveyormechanism designated generally by the letter A.

This-feed conveyor A delivers to the slicing table l8 (Fig. 3) of theslicer i when the slicer is in operative position or to thereciprocating transfer conveyor mechanism designated generally by theletter B, see Fig. 11. This transfer conveyor mechanism B delivers theloaves or articles to be wrapped to a conveyor designated by the letterC, see Figs. 4 and 11, by which conveyor the loaves are delivered to theelevator D, Fig. 4. This mechanism delivers the loaves to the wrappingmechanism designated generally by the letter E, Fig. 4, from which theyare delivered to the sealing mechanism designated generally by theletter F, Fig. 4. The sealing mechanism delivers the articles to thedelivery conveyor designated generally by the letter G, see Figs. 2 and3.

The feed conveyor mechanism comprises a feed table IS on which theloaves may be placed, a side or positioning bar 25 being arranged at therear of this table. The bottom conveyor belt 22 is supported at itsforward or outer end by the pulley 23 and at its inner end by the pulley25. This bottom conveyor belt 22 transfers the loaves from the feedtable l9 between the side conveyor belts 25 which engage the ends of theleaf and it is carried forward quite positively by the friction of thesebelts. When the slicing machine is in operative position the loaves arefed across the slicing table and into the knives of the slicingmachineby the pressure of succeeding loaves. This slicing machine unitis not described and illustrated in detail as it preferably embodies thefeatures of my application for Letters Patent generally by the numeral3! is provided for each feed conveyor side belt.

The pulley 23 is driven from the shaft 32, and

the shaft 33 is connected to the shaft. 32 by a variable speedtransmission gearing designated generally by the numeral 34, see Fig.2.v The shaft 33 is provided with universal joints 35. The shaft 33 isconnected to the pulley through a suitable gearing, the gear box 36 ofwhich is shown in Fig. 2. The pulleys 31 of the side conveyor-belts arethe driven pulleys and these pulleys are mounted on the vertical shafts38.

The shafts 38 have beveled gears 39 on their upper ends meshing with thegears 40 on the transverse shaft 4 l This transverse shaft is connectedby the sprocket chain 42 and suitable sprockets to a beveled gear 43which meshes with a beveled gear 45 on the end of the shaft 33 whichprojects from the variable speed transmission gear box. This feedmechanism, when operatively associated with the slicing machine, issubstantially that of my application for Letters Patent Serial No.654,481, filed January 31, 1933.

As stated, the feed conveyor may be adjusted to cooperate with theslicing machine or with certain of the conveyor features when theslicing mechanism is in inoperative position. This adthe loaves aredelivered from the slicing machine on to the delivery table 52. When theslicer is in inoperative position the loaves are driven.directly by thefeed conveyor to this delivery table 52.

The loaves, either sliced or Whole as the case may be, are deliveredfrom this table 52 to the conveyor slideway 53 of the conveyor C bymeans of transfer jaws 5G engaging the ends of the loaf at the positionshown by full lines in Figs. 9 and 11, carrying the loaf forwardly on tothe conveyor slideway 53. These jaws 54 are carried by arms 55 pivotedat 56 on the reciprocating carriage 51 which is mounted on the slideway58 disposed centrally above the path of the loaves. This carriageincludes a crosspiece 59.

The carriage is reciprocated by means of the arms 60 on the rockshafttil, the arms being connected to the cross piece 59 on the carriage bymeans of the links 62. The jaw arms are pivotally mounted on the outerends of the jaw supporting bars 53 which are slidably mounted on thecarriage for longitudinal adjustment. These bars are provided with racks55 coacting with a pinion having a shaft 65 provided with a handpiece 5?by means of which the jaw supporting bars may be adjusted to adjust thejaws to the length of the particular article to be wrapped.

When the frame 3 is retracted the- The opening and closing of the jawsis controlled by the reciprocation of the carriage. The closing of thejaws is timed by the article that is advanced either from the feedconveyor or through the slicer to position to be engaged by the jaws, aloaf of bread being indicated at I6, Fig. 9.

A trip 68 projects through a slot in the table 52. This trip is mountedon a rockshaft 69 having an arm I thereon connected by the link II to alatch lever I2 pivoted at I3. This latch lever coacts with the triplever I4 pivoted at 15 and actuated by means of the spring 16. The latchlever and the trip lever have coacting engaging parts as shown in Figs.9 and 14, the parts being shown in engagement in Fig. 14 and indisengaged position in Fig. 9. A weighted arm IT on the rockshaft 69,see Fig. 14, returns the trip and connected parts to initial position.

The trip lever I4 is connected by a link 18 to an arm I9 on therockshaft 8-0. Each jaw supporting bar 63 is provided with a head orbracket 8I at its outer end and carrying the pivot 56 for the jaw armand also slidably supporting a jaw controlling cam member 82 having acam recess 83 therein into which the roller 84 on the arm drops underthe action of the spring 85, thereby opening the jaws. The flat side ofthe cam member coacts with the roller to close the jaws. At the end ofeach forward stroke of the carriage the cam member engages the bumper86, see Fig. 9, and on the return stroke of the carriage engages withthe actuating tappet 81 providing that that tappet is in its actuatedposition.

The tappets 81 are mounted on a rockshaft 88 provided with a weightedarm 89 acting to swing the tappets to inoperative position. The tappetis shown in operative position in Fig. 9 and in inoperative position inFig. 11. The tappet is controlled through the trip lever mechanismdescribed, the rockshaft having arms 90 projecting forwardly therefromto be engaged by the spring extensions 9I on the arms 92 carried by therockshaft 8-0.

Referring to Fig. 9, it should be pointed out that the tappet is shownin actuated position by full lines and in normal or initial position bydotted lines, while the lever 92 is shown in its unactuated position,being held in this position by the detent 93 on the rockshaft 94. Thedetent 93 is tripped by the resetting dog 95 which is pivoted at 96 onthe head 8|. This resetting dog is controlled by the cam member 82 whichhas a recess 91 into which the roller 98 on the resetting dog drops whenthe cam member is actuated by coming into contact with the abutment 86,see the dotted position at the right of Fig. 9.

The resetting dog on the forward stroke of the carriage comes intocontact with the trip arm 99 on the rockshaft 94, swinging the detent 93out of engagement or into coacting relation with the lever I9, allowingthe lever to move upwardly to the dotted position under the action ofthe spring I6 and swinging the arm 92 downwardly to actuate the tappetto cam actuating position. The actuation of the cam member 82 by thetappet to close the jaws also lifts the resetting dog 95, which isdesigned to engage an arm I00 on the rockshaft 80, resetting or forcingthe arm I9 downwardly to be re-engaged by the detent The driving shaft32 for the feed conveyor is also controlled through this articlecontrolled trip mechanism. The rockshaft I has anarm engages aperipheral gear on the planetary drum I09 carrying the planetary gearsIIO. These planetary gears coact with a gear I I I keyed to the shaft H2and with the gear II 3 rotatable on the shaft but pinned to the drivengear II 4 meshing with the gear II5 on the shaft 32. It will be notedthat this shaft is provided with a universal joint IIS.

With this arrangement of the parts the feed conveyor is drivencontinuously through the mechanism described so long as the pawl I04remains in engagement through the connections described, preventing therotation of the planetary drum. However, when the pawl is disengaged,the planetary drum is free to rotate and this results in the stopping ofthegear I I3 of the planetary gearing and consequently the feedconveyor. This control. ashas been pointed out, is from the trip 68 sothat the feed conveyor is synchronized, either to feed the loaves to theslicing unit or directly to the table 52 in proper timed relation to beengaged by the jaws 54. These feed or transfer jaws 54 deliver to theconveyor way 53 of the conveyor C in timed relation so that the articlesare picked up by the flights I II on the conveyor chain H8. The transferjaws gripping the ends of the loaf deliver it between the side bars II9of the conveyor C between which it is carried along by the flights anddelivered on to the feed plunger or elevator I20 by which the loaves aredelivered to the wrapping mechanism E. A stop plate I 2| is provided toposition the articles on the elevator, the elevator having holders I22.

As the article to be wrapped is lifted by the elevator it is carriedagainst the under side of the wrapper and delivered with the wrapper tothe wrapping mechanism E. The wrapper, indicated at I23, is fed from theend of the machine, the roll being shown at I24. Feed rollers I25 andI26 deliver the-paper to the cutter, the roller I25 being a frictionroller and the roller I26 being preferably tubular to receive a chillingfluid, the connection being shown at I21, Fig. 1, so that the waxedpaper may be cooled or chilled where the machine is operating in suchtemperature as would soften the wax or paraflin. This prevents themachine from becoming clogged or gummed by the wax. The cutter I28 is ofthe rotary type.

The paper is delivered from the feed rolls to the wrapper conveyor beltI29 and by it projected or fed on to the reciprocating table I30. Thiswrapper supporting table is designed when in its actuated or forwardposition to receive the wrapper from the conveyor belt and effectivelysupport it, preventing its sagging into the space above the elevator.The wrapper supportingtable or slide reciprocates in the slideways I3Iand is operated from a lever I32 pivoted at I33 and connected by thelink I34 to the arm' I35 on the rockshaft I36 which is actuated from thearm I31 coacting with a suitable cam, not shown. This rockshaft carriesan arm I38 connected to the slide bar I39 of the elevator. This bar-likeslide of the elevator reciprocates in guides I40 carried by cross rodsI4I on the frame.

With this arrangement of parts the elevator and this paper receivingtable or slide are actuated in timed relation as the supporting slidemust be withdrawn to permit the elevator to deliver the article to bewrapped to the wrapping mechanism.

To position the paper as it is delivered from the paper feed belt Iprovide a stop I52 carried by the cross bar I65, this cross bar beingmounted on slides I45 provided with a rack I55 coacting with pinions M5.These pinions are provided with a handwheel I iI. This provides meansfor rapid adjustment of the stop to properly position the wrapper andprevent overthrow thereof. The paper is held against the feed belt I25to insure effective frictional engagement by means of the roller I55carried by the pivoted am it. The arm I59 of this friction roller iscarried by the adiustable'hanger I50 provided with a pivot IbI having anadjusting arm I52 thereon operatively associated with an indicia segmentI53.

By manipulation of this adjusting arm. I52 the arm I55 may be swims,thereby positioning the roller use relative to the feed belt anddetermining the point at which the frictional engagement of the paperwith the feed belt terminates, stopping the feed of the paper.

The loaf or article to .be wrapped is delivered by the article feedconveyor or elevator between the pusher I545 and the holder jaw I55opposed thereto, see Fig. 4. The pusher is adjustably mounted on thecarriage designated generally by the numeral I55. vided for securing thepusher tothis carriage. The opposed holding jawI55 is pivoted at I58 onthe frame and is adapted to be swung upwardly out of the way of thearticle as it is carried forr the wrapper carr age. li'l ie i a ottomflap folder is indicated at I59, the front end flap folders at I60, thetop end flap folder at I5I and the front end flap folders at I52. Thesefolders form no part of my present invention and are not described withfurther detail. It will be understood, however, that the bottom folderI59 is actuated in proper relation to the movement of the feed plungerso that it serves as a support for the article when the plunger is a teT hg g ipper I55 is actuated in timed relation to the movement of thecarriage so that it is swung upwardly out of the path of the article tobe wrapped but keeps a holding engagement with the front side thereofuntil the front portion of the wrapper is engaged by the front edge ofthe alin wa I55. Frol n th final end flap folders I62 the article isdelivered between the end sealers which. in the preferred embodiment ofmy invention comprise a plurality of sealing bars I65 disposed inparalllel relation and mounted on double eccentrics I55 and I57, seeFigs. 5 and 6. It will be noted that alternating bars are mounted on theeccentric straps I65. The eccentrics are carried by vertical spindlesI'III having parts III at their lower ends slidably mounted on'the shaftH2 and the cross rod IIS on the frame so that the sealer units may beadjusted to and from each other. The

spindles are connected at their upper ends by the housings or guards I13mounted upon the reduced upper ends of the spindles and secured theretoby the nuts Hit.

The eccentrics I55 have sleeve-like extensions I15 at their lower endsprovided with beveled gears I76 meshing with the gear ill on the shaftI72. The double eccentrics are so disposed that one set of sealer barsis advanced into loaf-engaging position when the other ie retracted. The

A clamping means I5? is prosealer bars are given an orbital movement,that of the sets of bars alternating so that the loaf or article beingsealed is constantly engaged by sealer bars and moved forwardly owing tothis alternate engagement of thesets of bars, the forward motion beingsubstantially continuous.

With this arrangement there. is no sliding engagement of the wrapperwith the sealers, the motion of the sealer bars being such that asubstantial period of contact is maintained but without wiping orsliding engagement. The sealer bars are electrically heated by heatingelements designated generally by the numeral I19.

The bottom seal is effected in a similar manner, that is, thefinger-like bottom sealers I80 are pivotally or rockingly mounted on therod I8I carried by the arms I82 on the cross rod I83. This cross rod ismounted on the carriers I86 slotted at I85 to engage the support I86 andsupported at the other end by the eccentrics I81 fixed to the shaft H2and engaging a suitable bearing I89 on the supports, see Fig. 5. Thesealer members I80 are independently pivoted on the rod I8I and areurged yieldingly upward by means of the springs I90 secured at one endto the pin I9I on the stop arm I92 and at the other end to pins I93provided therefor on the rod I83. The stop arm is adapted to coact withthe cross rod I83 to limit the upward movement of these sealer members.The shaft II is a. tubular shaft, the heating element I8 I beingarranged therein as shown in Figs. 5 and 8.

With this arrangement the sealing fingers I80 are given an orbitalmotion, their forward movement taking place while they are at the upperreach of their stroke, so they travel with the article being sealed. Thesealing fingers yield so that they conform to an irregular or yieldingsurface. such as a loaf of bread, and supply sufficient pressure tomaintain contact for such period as will insure effective sealing.

During its passage through the sealing mechanism the bread or otherarticle being wrapped is urged downwardly by means of the pressure barsI95 which are pivoted at I95 on. the hanger arm's I95, which are in turnpivoted at I91 on the housings I13. The adjustable rests I98 in the formof screws are threaded through suitable bosses or enlargements I99 onthese arms, the screws resting on the top of the housings. This limitsthe downward movement of the pressure bars so that the article can bewrapped and later pass under the forward ends of the bars which arepreferably upturned as indicated in Fig. 5.

The housings I13 serve as guards for the sprocket chains 200 which coactwith the sprocket wheels 2M which are secured to the eccentrics I56andI61.

By this arrangement the sealing both at the ends and bottom is effectedby means which, in effect, travel with the article being sealed so thatthere is no tendency for displacement of the folds for the wrapper or todisplace the wrapper on the wrapped article.

These sealingelements deliver the wrapped sealed article to the deliveryconveyor G, which comprises the slideway 202 and side conveyor belts 255and 2%, there being a pair of these side conveyor belts at each side ofthe way. These side conveyor belts are continuously driven,

and the pulleys 205 mounted on vertical shafts the feed conveyor belt isdriven by the mechanism previously described.

The delivery conveyor belts 203 and 204 are provided with suitable belttighteners designated generally by the numeral 2| I, see Fig. 2, thepurpose of this being to secure the desired tension to engage the upperand lower portions of a wrapped loaf of bread, the upper portion ofwhich may be bulged or enlarged relative to the lower portion.

The pulleys at the outer ends of the belts 203 and 204 are driventhrough the shafts 2I2 connected to the upper ends of the shafts 206through suitable gearing, designated generally by the numeral 2-I3,housed within a gear box as illustrated. The shafts 212 are connected tothe shafts 2 I4 for these outer pulleys through gearing designatedgenerally by the numeral 2I5. This arrangement permits the inner reachesof the belts to be kept taut and in supporting driving engagement withthe ends of the sealed artithe brackets or supports carrying the sidebars cles.

nected by the sprocket chain 222 to the adjusting screw 223 for thefolders I60 and I6I and the grippers I55, and to the screw shaft 226 forN9 of the conveyor C.

The rear flap folders I62 are mounted on forwardly projectingbracket-like arms on the housing members I13 to be adjusted with theside sealers. This adjustment is effected through the shaft I86.

The forward ends of the side bars H9 are carried by the hangers 225whichare bracket extensions on the side sealer supports. The shaft I86performs the double function of slidably supporting the ends of thecarrier I, see Fig. '7,

and has an adjusting screw, portions only of the shaft being threaded.

Through this arrangement of parts the mechanism is adjusted fordifierent lengths of loaves through three adjustments, the feed conveyorthrough the handwheel 30, the transfer jaws through the adjusting member61 and the parts just described through the handwheel 22L To accommodateloaves of difierent widths the abutment plate I2! is adjusted, thisplate being carried by a sliding bracket 228 mounted on the slide 221and provided with an adjusting lever 22B pivoted at 229 and having aslotted segment 232 and coacting locking screw 23L The supporting slidefor the abutment I2I is provided with a pointer 232 coacting with a gage238.

The feeding of the paper is controlled from the trip 2% pivoted at 235and provided with a return counterweight 286, see Fig. 1. This trip isconnected by the link 23'! to the clutch mechanism 238. The clutchmechanism drivesthe paper feed rolls through the shaft 239 which isconnected by the chain 240 and suitable sprockets to the shaft 2M of thelower cutter roll 222, which coacts with the cutter roll I 28. Thesecutter rolls are connected by the gears 243 and 248, while the feed milsI25 and I26 are connected to the cutter roll I28 by a suitable variablespeed gearing designated generally by the numeral 245. The purpose ofthis variable speed'gearing is to vary the speed of the feed rolls andthereby vary the size of the wrapper.

The driving pulley or roller 248 for the paper feed belt I29, which ispreferably a plurality of belts in the form of coiled springs, isconnected to the gear 243 by means of the gear 241. The paper feed beltis thus driven only through the wrapper feed control clutch, the objectbeing to stop the paper feed belts when the paper feed is stopped andthus prevent the wear on the wrapper or the distortion of the wrapperwhich would result from continuous driving of the paper feed belts withthe paper feed rollers at rest.

It will be noted by reference to Fig. 16 that the bottom flap folder I59is the full width of the wrapper and that the first bottom fold isfolded or wrapped-over the plunger I20, the movement of which is timedso that .the wrapper is drawn around the edge thereof as shown in Fig.16. This acts to maintain the wrapper smooth throughout the widththereof and secures a highly desirable fold and close wrapping, which isof advantage particularly in sliced loaves of bread where close wrappingserves to maintain the shape of the loaf, notwithstanding its slicedcondition.

In the embodiment of my invention shown in Figs. 17 and 18 the sealermembers 248 are in the form of rollers or disks disposed in interlappingrelation so as to present a fairly continuous forwardly moving surfaceto the article to be sealed. The shafts 249 of these rollers areprovided with plnions 250 meshing with the worm gears 2H on the drivingshafts 252 so that the sealer members are all driven in the samedirection and at uniform speeds. This results in translating thearticles to be sealed through the sealing mechanism without wipingcontact, as has been the practice heretofore so far as I am aware, whichresults in more or less distortion and displacement of the wrapper andconsiderable irregularity in sealing.

With my sealing mechanism the heated sealer elements travel with thearticle when in engagement therewith and serve as driving elements. Thisresults in a very effective and uniform sealing of a plurality ofsuperimposed or overlapped flaps and, as stated, without distortion ordisplacement thereof.

My combined slicing, wrapping and sealing machine is highly efficientand may be quickly adjusted for the combined functions of slicing,wrapping and sealing, or for wrapping and sealing, thus adapting themachine for use in bakeries where bread is sold-in both forms, which isin fact the common practice.
